Please show work. Will give thumbs up.

A particular fruit's weights are normally distributed, with a mean of 255 grams and a standard deviation of 7 grams. If you pick one fruit at random, what is the probability that it will weigh between 256 grams and 260 grams Calculator Delivery times for shipments from a central warehouse are exponentially distributed with a mean of 1.58 days (note that times are measured continuously, not just in number of days). A random sample of 50 shipments are selected and their shipping times are observed. Approximate the probability that the average shipping time is less than 1.28 days. Enter your answer as a number accurate to 4 decimal places. Calculator > Next
